{"id":"DEBIAN-CVE-2026-41567","details":"Moby is an open source container framework. In versions prior to 29.5.1 and in moby/moby v2 prior to v2.0.0-beta.14, when a compressed archive is uploaded to a container via `PUT /containers/{id}/archive` or piped through `docker cp -`, the daemon resolves decompression binaries (such as `xz` or `unpigz`) from the container's filesystem rather than the host's due to incorrect ordering of operations. A malicious container image containing a trojanized decompression binary can achieve arbitrary code execution with full daemon privileges, including host root UID and unrestricted capabilities, when a user uploads a compressed (xz or gzip) archive into that container. This issue is fixed in Docker Engine 29.5.1 and moby/moby v2.0.0-beta.14. Workarounds include only running containers from trusted images, using authorization plugins to restrict access to the `PUT /containers/{id}/archive` endpoint, and avoiding piping compressed archives into containers created from untrusted images","modified":"2026-09-10T08:47:23.371321489Z","published":"2026-06-05T02:17:13.817Z","upstream":["CVE-2026-41567"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-41567"}],"affected":[{"package":{"name":"docker.io","ecosystem":"Debian:12","purl":"pkg:deb/debian/docker.io?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["20.10.24+dfsg1-1","20.10.24+dfsg1-1+deb12u1","20.10.25+dfsg1-1","20.10.25+dfsg1-2","20.10.25+dfsg1-3","20.10.25+dfsg1-4","26.1.4+dfsg1-1","26.1.4+dfsg1-2","26.1.4+dfsg1-3","26.1.4+dfsg1-4","26.1.4+dfsg1-5","26.1.4+dfsg1-6","26.1.4+dfsg1-7","26.1.4+dfsg1-8","26.1.4+dfsg1-9","26.1.4+dfsg2-1","26.1.4+dfsg3-1","26.1.5+dfsg1-1","26.1.5+dfsg1-10","26.1.5+dfsg1-2","26.1.5+dfsg1-3","26.1.5+dfsg1-4","26.1.5+dfsg1-5","26.1.5+dfsg1-6","26.1.5+dfsg1-7","26.1.5+dfsg1-8","26.1.5+dfsg1-9","27.5.1+dfsg1-1","27.5.1+dfsg1-2","27.5.1+dfsg2-1","27.5.1+dfsg3-1","27.5.1+dfsg3-2","27.5.1+dfsg3-3","27.5.1+dfsg3-4","27.5.1+dfsg3-5","27.5.1+dfsg3-6","27.5.1+dfsg4-1","27.5.1+dfsg4-2","28.5.2+dfsg1-1","28.5.2+dfsg2-1","28.5.2+dfsg3-1","28.5.2+dfsg3-2","28.5.2+dfsg4-1","28.5.2+dfsg4-2","28.5.2+dfsg4-3","28.5.2+dfsg4-4"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-41567.json"}},{"package":{"name":"docker.io","ecosystem":"Debian:13","purl":"pkg:deb/debian/docker.io?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"26.1.5+dfsg1-9+deb13u1"}]}],"versions":["26.1.5+dfsg1-9"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-41567.json"}},{"package":{"name":"docker.io","ecosystem":"Debian:14","purl":"pkg:deb/debian/docker.io?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"28.5.2+dfsg4-3"}]}],"versions":["26.1.5+dfsg1-10","26.1.5+dfsg1-9","27.5.1+dfsg1-1","27.5.1+dfsg1-2","27.5.1+dfsg2-1","27.5.1+dfsg3-1","27.5.1+dfsg3-2","27.5.1+dfsg3-3","27.5.1+dfsg3-4","27.5.1+dfsg3-5","27.5.1+dfsg3-6","27.5.1+dfsg4-1","27.5.1+dfsg4-2","28.5.2+dfsg1-1","28.5.2+dfsg2-1","28.5.2+dfsg3-1","28.5.2+dfsg3-2","28.5.2+dfsg4-1","28.5.2+dfsg4-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-41567.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:C/C:H/I:H/A:N"}]}
